Anomalous self-steepening, temporal pulse splitting and ring formation in a left-handed metamaterial with cubic nonlinearity
Ajit Kumar, Akhilesh Kumar Mishra
In this paper, starting with the Maxwell equations and the corresponding nonlinear wave equation, we derive a pulse evolution equation for a metamaterial with cubic (Kerr) nonlinearity. The given model equation goes beyond the commonly employed slowly evolving wave approximation (SEWA). The ... [J. Opt. Soc. Am. B 29, 1330-1337 (2012)]

Supermodes of hexagonal lattice waveguide arrays
J. Scott Brownless, Felix J. Lawrence, Sahand Mahmoodian, Kokou B. Dossou, Lindsay C. Botten, C. Martijn de Sterke
We present a semianalytical formulation for calculating the supermodes and corresponding Bloch factors of light in hexagonal lattice photonic crystal waveguide arrays. We then use this formulation to easily calculate dispersion curves and predict propagation in systems too large to calculate using ... [J. Opt. Soc. Am. B 29, 1338-1346 (2012)]

Localized surface plasmon modes in a system of two interacting metallic cylinders
Viktoriia E. Babicheva, Sergey S. Vergeles, Petr E. Vorobev, Sven Burger
We study an optical response of a system of two parallel close metallic cylinders having nanoscale dimensions. Surface plasmon excitation in the gap between the cylinders is specifically analyzed. In particular, resonance frequencies and field enhancement were investigated as functions of ... [J. Opt. Soc. Am. B 29, 1263-1269 (2012)]

Modeling of amplified spontaneous emission, heat deposition, and energy extraction in cryogenically cooled multislab Yb^3+:YAG laser amplifier for the HiLASE Project
Magdalena Sawicka, Martin Divoky, Jakub Novak, Antonio Lucianetti, Bedrich Rus, Tomas Mocek
A three-dimensional ray-tracing code for determination of amplified spontaneous emission in a multislab laser amplifier is presented. In addition to energy stored in the amplifier, the code also calculates the heat distribution and the amplification of the signal beam. For cryogenically cooled ... [J. Opt. Soc. Am.

Application of optical-field-ionization-induced spectral broadening in helium gas to the postcompression of high-energy femtosecond laser pulses
Thierry Auguste, Oliver Gobert, Coralie Fourcade Dutin, Antoine Dubrouil, Eric Mével, Stéphane Petit, Eric Constant, Dominique Descamps
We report a detailed numerical study on the postcompression of high-energy (?30?mJ) femtosecond laser pulses (?40?fs), using the spectral broadening induced by optical-field ionization of a low-pressure helium gas in a capillary. Our numerical results are in very good agreement with ... [J. Opt. Soc. Am. B 29, 1277-1286 (2012)]

Dielectric waveguide bending adapter with ideal transmission: practical design strategy of area-preserving affine transformation optics
Hongyi Xu, Baile Zhang, Tianyuan Yu, George Barbastathis, Handong Sun
Transformation optics has inspired numerous conceptual devices since the first theoretical model of invisibility cloaks. However, the transition of these concepts into industrial applications is now widely acknowledged as a challenging bottleneck. A practical design strategy that can be adopted by ... [J. Opt. Soc. Am.

Optical bistability based on guided-mode resonances in photonic crystal slabs
Quang Minh Ngo, Khai Q. Le, Vu Dinh Lam
Optical bistability of nonlinear guided-mode resonances in photonic crystal slabs (PCSs) are numerically investigated. We perform finite-difference time-domain simulations to determine the linear and nonlinear characteristics of these guided-mode resonances in PCSs. The nonlinear characteristics ... [J. Opt. Soc. Am.

Efficient Lanczos?Fourier expansion-based transmission line formulation for full-wave modal analysis of optical waveguides
Amir Habibzadeh-Sharif, Mohammad Soleimani
The Fourier expansion-based transmission line (TL) formulation has been modified using the Lanczos correction factor for the full-wave modal analysis of dielectric optical waveguides. Also, an algorithm for systematic determination of the optimum values for the main simulation parameters of the ... [J. Opt. Soc. Am. B 29, 1296-1304 (2012)]

Scattering in step-index polymer optical fibers by side-illumination technique: theory and application
M. Asunción Illarramendi, Gotzon Aldabaldetreku, Iñaki Bikandi, Joseba Zubia, Gaizka Durana, Amaia Berganza
In this paper we present a detailed theoretical study that describes the generation of scattered light in step-index polymer optical fibers by using the side-illumination scattering measurement technique. A detailed analysis of the variation of the maximum angle of acceptance within the fiber has ... [J. Opt. Soc. Am. B 29, 1316-1329 (2012)]
